Erosional caves can be found in almost any kind of rock, from hard granite to soft claystones, and even including limestone. In fact erosion can be a very active process in caves originally formed by solution caves as well, but usually occurs after the cave has drained and surface streams are pirated into the cave. Erosion tends to produce tall, canyon-like passages. Running water on glaciers may sink into crevasses and melt a path through the glacier to form glacier caves. These often show pronounced scalloping on the walls and ceilings, and are often decorated with ice formations.
How Caves Form. Molten lava, crashing waves, seeping rainwater, and oil-eating bacteria: These are some of the forces of nature that, over many years, create caves from rock like limestone and sandstone. In this interactive, explore the geology behind four different types of cave formation.
